“Consumption of tree nuts should be encouraged as part of a healthy diet by health professionals to improve diet quality and nutrient adequacy,” said Carol O’Neil, professor at Louisiana State University’s agricultural centre.

He also stressed the need for nutrition education programmes that increase awareness and consumption of tree nuts.

The team found that when it comes to nutrient adequacy for most nutrients, tree nut consumers fared better than non-consumers.

“This new research further supports the need to encourage people to eat tree nuts for overall health,” stated Maureen Ternus, executive director of the International Tree Nut Council.

We need to encourage people to grab a handful of nuts every day, he added.
